Stent-Assisted Balloon-Induced Intimal Disruption and Relamination in Aortic Dissection Repair: The STABILISE concept
Conclusions: The Stent-Assisted Balloon-Induced Intimal Disruption and Relamination in Aortic Dissection Repair approach is a feasible endovascular technique that shows promise to achieve complete repair of the dissected aorta by inducing complete false lumen obliteration. The restoration of uniluminal flow in the thoracoabdominal aorta has the potential to improve long-term outcomes. Prospective, multicenter investigations are required to implement this strategy more broadly.

Outcomes of off-pump versus on-pump coronary artery bypass grafting: Impact of preoperative risk
Background: It is unknown whether purported benefits of off-pump coronary artery bypass grafting are patient-specific within the Society of Thoracic Surgeons National Cardiac Database or dependent on center volume or operating surgeon.Methods: The Society of Thoracic Surgeons National Cardiac Database was queried for all patients undergoing nonemergency, isolated coronary artery bypass between January 1, 2005, and December 31, 2010, who had Predicted Risk of Mortality scores and participant/surgeon identifiers. Of these 876,081 patients (“all sites”), 210,469 underwent surgery at participant sites that had performed mo...

Predictors of electrocerebral inactivity with deep hypothermia
Conclusions: Cooling to a nasopharyngeal temperature of 12.7°C or for a duration of 97 minutes achieved ECI in>95% of patients in our study population. However, patient-specific factors were poorly predictive of the temperature or cooling time required to achieve ECI, necessitating EEG monitoring for precise ECI detection.

Hybrid repair of Kommerell diverticulum
Conclusions: Hybrid repair is a safe and effective surgical treatment option for Kommerell diverticulum. Selection of the specific type of intervention is based on patient anatomy and comorbid conditions.

Systematic review of outcomes of combined proximal stent grafting with distal bare stenting for management of aortic dissection
Conclusions: Combined proximal stent grafting with distal bare stenting for management of aortic dissection appears to be a reasonable approach for type B aortic dissection, clearly improved true-lumen perfusion and diameter although failing to suppress false-lumen patency completely. Contemporary information on this approach is mainly provided by small series with a wide range of results.

Trends in aortic clamp use during coronary artery bypass surgery: Effect of aortic clamping strategies on neurologic outcomes
Conclusions: During on-pump coronary artery bypass grafting, the use of a single crossclamp compared with the double clamp technique decreased the risk of postoperative stroke. The use of any aortic clamp decreased and epiaortic ultrasound use increased from 2002 to 2009, indicating a change in the operative technique and surgeon awareness of the potential complications associated with manipulation of the aorta.

Left ventricular efficiency after ligation of patent ductus arteriosus for premature infants
Conclusions: Analysis of indices representing the afterload, contractility, and energetic efficiency of the left ventricle may provide practical information for the management of premature infants during the postoperative period after patent ductus arteriosus ligation.

Minimally invasive approach provides at least equivalent results for surgical correction of mitral regurgitation: A propensity-matched comparison
Conclusions: In appropriate patients with isolated mitral valve disease of any cause, a right minithoracotomy approach may be used without compromising clinical outcome.

Transcatheter aortic valve implantation: Clinical evidence versus clinical practice
Enthusiasm and use of transcatheter aortic valve implantation (TAVI) have grown exponentially since the first TAVI procedure was performed a decade ago. Critics of this relatively novel technique, however, argue that clinical practice has far outpaced robust clinical evidence. The recent summary by Agnihotri provides a broad overview of the recent consensus statement approved by a dozen professional societies, including the American Association for Thoracic Surgery. Agnihotri correctly emphasizes the subjectivity of the patient selection process for TAVI and a number of postprocedural complications such as stroke, requirem...

Control of ventricular unloading using an electrocardiogram-synchronized Thoratec paracorporeal ventricular assist device
Conclusions: The timing of pump ejection in synchronized mode yields control over left ventricular energetics and can be a method to achieve gradual reloading of a recoverable left ventricle. The traditionally suggested counterpulsation is not optimal in ventriculo-aortic cannulation when maximum unloading is desired.

Effect of intensive care unit environment on in-hospital delirium after cardiac surgery
Conclusions: The intensive care unit environment did not have a significant effect on the overall prevalence of delirium. However, that does not preclude the possibility that the intensive care unit environment might interact with other factors, such as age, in a complex manner. Attempts to reduce delirium by adjusting the intensive care unit environment alone will likely not be sufficient, and instead will require a more comprehensive multimodal approach.

Outcomes of contemporary emergency open surgery for type A acute aortic dissection in elderly patients
Conclusions: Emergency open surgery for type A acute aortic dissection in elderly patients resulted in a low mortality but high incidences of stroke and prolonged hospital stay. Preoperative cardiopulmonary resuscitation and previous cardiac surgery were significant predictors of stroke. Emergency surgery is still the primary option for most elderly patients with acute aortic dissection.

Optimal treatment strategy for type A acute aortic dissection with intramural hematoma
Conclusions: Emergency surgery for patients with type A IMH showed favorable mortality rates because most of the patients were in hemodynamically stable condition preoperatively. On the other hand, several patients died suddenly during medical care. Emergency surgical treatment may provide a better outcome than medical treatment at the time of onset, even for patients with type A IMH.

Restraint to the left ventricle alone is superior to standard restraint
Conclusions: We showed previously that, with standard restraint, right ventricle tamponade develops at high restraint levels, limiting restraint therapy. We now show that restraint applied to the left ventricle alone permits increased restraint levels, without causing right ventricle or left ventricle tamponade, for greater therapeutic benefit. We conclude that partial left ventricle restraint may be more effective than standard restraint.

Clinical outcomes of aortic root replacement after previous aortic root replacement
Conclusions: Aortic root replacement after a previous aortic root replacement is associated with a relatively low operative mortality and perioperative morbidity, but long-term survival is suboptimal. Increasing age and prosthetic valve endocarditis adversely affect survival.
